ELECTRIC WATER-PURIFIER.

. Specification of Letters Patent. Iatellfcd D131', 25, 1913.

Application filed June 29, v1912. Serial No. 706,775.

To all lwhom it may concern y Be it known that I, ADA H. VAN PEL'r, acitizen ofthe United States, and resident of 'Los Angeles, in the countyof Los Angeles and State of California, have invented certain new anduseful Improvements in Elec-` ltric Water-Purifiers, of which thefollowing is a specification.

My invention pertains to waterfpurifying apparatus, and it has specialvre ereiice to mechanism for purifying water by electrolysis, Vand thedevice is of such a character `as to be portable and applicable for usein small-vessels, so as to adapt it for domestic and other uses. l, .A

'The invention comprises a metallic disk which also serves as a base,which .has centrally an upwardly-projecting tubular stem, g preferablyof insulating material, this stem carrying vthereon ,a vertically-adjustablef spider, -the arms of which are ofsuitablel metal, and incoiiiiectinor up .the base thus Aformed and the'spider with a suitablesource of electricity, so that when the device thus constructed isimmersed in water and a current sent through theV saidl electrodes, the

usual electrolytic effect will be produced in the water, and the samepurified in a manner well known to the art.

It also provides a means whereby, instead of filtering the product, areservoir may be used in connection with the purifier, which will catchthe precipitate, and t-hus enable .a disk 3, preferably of aluminum, ofany suitable diameter, which has, for convenience, a set of down-turnedmembers 4 to v serve as legs, so that it may be slightly elevated abovethe base which supports the device. This has a plurality of perforations5 therein so water may freely circulate from one side to the other. l

Centrally the disk has a hole and an upturned annular flange 6,surrounding the fthe water to be drawn therefrom at' any time` after thewater has been purified, all of hole, adapted to receive therein thelower, end of a tubular stein 7. This stein may or may not be ofinsulating material, but in this instance, I show it made preferably ofhard rubber, the upper end being open and designed I to receive aremovable .head S, through which the inlet wires pass. One ot' theseinlet wires-9 passes down through the tube and is held by a screw -10which passes through the flange 6 of the disk 3, and Vthe other wireconductor l1, connects throughv the sci'ew 12, with ,a metal Contact bar13 whichvils secured to the oiiter surfaceof the tubular stem forpurposes which will be hereinafter explained. .On this stem is mounted avertically movable and adjustable spider, this spider being preferablyin the shapeof a circularly-formed body of 4insulating material 14,which has a vertical notch 15, within the hole, so as to clear thecontact bar 13 on the side of the stem. This body has a set screw 16through one side, which is designed to have its endcontact wit-li thetubular stein, so as to provide means for vertically adjusting thespider, and thus enable me to provide a means for regulating thedistance between the spider and base disk.

The body 14 has secured therein a plurality of radiating arms`17, of anysuitable metalA or corthvoi of electricity, each arm being heldin placeby a set screw 1S, each set screw passing through a ring 19 on the upperside of the body 14, so that the arms are thus electrically iii Contacttherewith. At one side, the metal ringI has an upwardlyprojectingcontactfinger 20 to engage with the vertically-disposed contact bar on theoutside of the stem,

From the foregoing it will be seen that one conductor is in electricalcontact-with the base, which base constitutes one of the terminals, andthe other conductor is electrically connected with the arms of thespider, so that the latter constitute the other terminal of theelectrical device. As the difi'erent waters which are to be treated havedifferent resistances, I am enabled by the' vertical adjustmentpf thespider to.so tix the distances between the terminals as to give the moste'ective treatment. to the water, and it is also obvious that asdifferent.

voltages are found in electric systems, it is essential that thisadjustable means is a necessary element in providing a device of thischaracter. As the device is applicable for either alternating or directcurrents, I separate the terminals inucli farther apart, when vanalternating 'current is used, so. that the terminals may be adjusted tomalte the water 5 itself act as the resistance, and thus preventoverheating. By this arrangement of the spider terminal it is acoiiipaiativeiy easy matter to remove`citlier of the arms, and replacetliesaiiie, wliile the base iiseliC can be replaced ivitli equalfacility; without in any manner disturbing the electrical connections.

In use the device t-lius constructed is designed to be immersed iiiwater contained in. any 'suitable vessel, as at 21, but in order toprovide a means whereby no filtration is `required, l construct areservoir 522,'wli'icli is in the form of a cylindrical shell with afunnel shaped bottom 23, provided -ii-'itli a 20 -plug valve 24. Thebottom of the shell has 1i' a narrow annular ledge on which the legs iof the purifier-base rest. The object of this .f. funnel-sliaped baseis. to receive the deposi- 1 1.- tion producedbythe purifyiii`,f rtreat-ment, and the purified water may be drawn from the reservoirthrough the cock 26, at the side of-.tlie cylinder. AThe centi-al stemof the purifier passesithrough the cover Q7 of the reservoir and thestein. and cover are prefertioyabl secured to 'each other, so that tliecover aiidlplirifier are both lifted out together. Thev reservoiry thusconstructed may be s mounted-'on any suitable stand or base 28,as.,sliown, and in' practice a drain pipe 2S), `5frorn'tliegliiss stand30 may extend down andconnectwithihe discharge pipe of the reservoirbelow the valve 241i..v lVliatrIj claim as new, is 1 w `'1.
